I have a very rare NOS 1970 aluminum intake manifold for sale. Dated 8/13/69. $2,900 plus shipping charges.

firefrost gold

wow he wants that much or wow that's a cool part ?

scottv442

wow....don't see these too often.

wow ouch...these intakes are going sky high in prices now.

jensenracing77

Very cool! I have seen many of these NOS but never an NOS one dated 1969.

rsherman

This intake was wrapped up in plastic in the trunk of a Rally 350 that I purchased 15 years ago. I no longer have the car. I would like to add that I am asking $2,900 or best acceptable price.

Drbigblock

HI I’m interested in the intake
Here’s my emal heeepmaster@gmail.com
I’ve had no luck in sending you a pm

rsherman

Yes, Drbigblock I did get your PM. I sent you my email address. Thanks

rsherman

Dave, I would be very interested in your research on this intake. A couple of things I would like to know.
With the date code of 8/13/69. Could it be date coded correct for a late 69 as well as a 70 W-31.
I was told that it was not the right application for a Rally 350. If that is correct what would be the correct application?

The first w31 intakes were made in August of 1969, and were casted until to mid 1970s. They were exclusively on 1970 w31s. Hope this info helps

rsherman

Joesw31, yes that helps. So that would make this intake cast in the very first month of production August 13, 1969. I wonder if anyone knows of an earlier dated intake. Thanks

oldsmobiledave

The W-350 intake for my 1970 Cutlass W-31 was cast Aug 27 1969 so you got me beat by 2 weeks.

joesw31

Most of the W31 intakes were casted in August. However, I have seen September, and October. And in April they changed casting numbers on the intake, that differed slightly. Hope this helps

jensenracing77

You have me beat by a day. Mine is 8-14-69

rsherman

Wow, that’s really neat (one day). I may be shooting myself in the foot. But, what do you do with a low production NOS 48 year old special W-31 intake?
Hang it on the wall?

Toms cutlass

I don't know the date of my W-31 manifold. It's installed.

jensenracing77

Yep!

joesw31

You can as Eric did. The intake is worth what the market will bare. If the intake was for a w30, then, I am sure it would had been sold. I was curious is the carburetor mounting flange pitted?

rsherman

It does have some texture to it. It is not perfectly smooth. Like small machined grooves. I will be home on Tuesday and will post some better close up pictures.

rsherman

joesw31 If you look at post 17 and zoom in on the carb mounting area you will see the same machined finish. Also on post 16 but not quit as prevalent.

joesw31

In your pictures the carb mounting area appears to have some pits, but it could be the picture. Good luck with your sale.

I had one of these I bought about 14 years ago for $500 that I was going to put on a 1971 Supreme Convertible. After deciding that was a stupid thing to do, I sold it for the same price to someone who had a 70 W-31 (which is where a piece like this belongs IMHO). And that was 13 years ago. Wow, just to see one NOS, nicely done!

marxjunk

i remember seeing them in Hemmings all the time back before ebay took off..there was always a few NOS on there it seems to me...back then, which would be 95 ish they where always $500+

stevengerard

Yep, if we even knew! Seems in the 90s all these parts were already "expensive" already! in reality with the inflation some of these parts are still the same but some have gone through the roof. I can't tell you how many swap meet W31 manifolds I didn't buy - let alone Cutlass pace cars and Rallye 350s for less than 10k.

rsherman

Ctls442, Sorry I could not PM you back for some reason. Please send me your email and I will send you some more pictures.
FYI, I am a 95% Ford guy. But, I have got to say you GM guys are okay.

I have one that also has the 8.14.69 date.

rsherman

Close, but still winning by one day. Still can’t help but wonder if August 13, 1969 could have been the first casting date. I don’t see that making any difference in value. Just curiosity sakes.

rsherman

I really have no idea what the value is on this NOS intake. I understand that it is worth whatever someone is willing to give. But, for now I am changing the price to $2,500 plus shipping charges. Thanks

Factoryhotrod

It is worth every bit of your price. NOS. Good luck with your sale.

rsherman

Toms cutlass

What then is the market value (sale price) for a NOS W-31 intake manifold?
